In the paper, an attention is paid to hybrid (lumped-distributed) systems with the MTLs as their distributed parts, whereas parameters of the system can vary randomly. In case of the MTL itself, with rather simple terminating elements, just the SDE theory would be applicable when taking into account some proper numerical technique. Usually, evaluation of the dispersion of responses of the system is needed which can be resolved via confidence intervals determination. To do it, either the solution of the SDE and subsequent statistical processing is applied or the direct solution of variances via Lyapunov-like equations can be performed. In hybrid systems, however, due to lumped-parameter parts included, a non-differential (algebraic) part is generally present in respective mathematical model. Therefore, a stochastic differential-algebraic equation (SDAE) approach has to be considered. The SDAE solution is more complicated in general while a proper numerical technique has to be chosen. In this paper a way of direct solution of variances and confidence intervals is elaborated to be able to avoid the SDAE solution itself, namely by formulating and numerically solving Lyapunov-like equations adapted for hybrid MTL systems. All the computations are done by using the Matlab language, with some examples provided.
